VALVED FLUE.

Application filed June l, 1915.

To all tf1/0m t may concern Be it known that I, HALLECK J. Dn LONG, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of vOlhio, have invented certain new and useful Improvements in Valved F lues; and l hereby declare the following to be a full, clear, and exact description of the invention, such las will enable others skilled in the vart to which it pertains to make and use the same.

This invention. relates to improvements in valved lines, and more especially to a valved iiue adapted to conduct gases from a blast-furnace.

@ne object of this invention is to have said lue comprise not only two flue-sections which are arranged in line and spaced endwise and participate in the formation of a passageway for conducting fluids, but to have said flue provided with a rotary dislivalve adapted to control communication and arranged between said flue-sections and operatively connected with a suitably rotated shaft arranged externally of the flue.

Another object is to have said valve supported externally of the aforesaid passageway so that the bearing of the valve is not exposed directly to fluid conducted through the passageway.

Another object is to have adjacent endportions of the aforesaid flue-sections contoured as required to permit the use of a valve which is not objectionably large in diameter.

Another object is to provide improved means for establishing a tight joint between the valve and said flue-sections in either position of the valve and for loosening said valve relative to said flue-sections preparatory to the actuation of the valve from-one to the other of its positions.

Another object is to render my improved valved iiue simple and durable in construction. i

With these objects in view, and to the end of attaining any other advantage hereinafter appearing, this invention consists in certain features of construction, and combinations and arrangement of parts, hereinafter described, ypointed out in the claims and illustrated in the accompanying drawings. i

ln said drawings,

ing my invention, and in this figure the valve is shown in its open position. Fig. 2 is a side view of said flue. Fig. 3 is a vertical section on line 3h23, Fig. 2, looking in the direction indicated br the arrow. Fig. 4 is a vertical section on line H, Fig 3, looking in the direction indicated by the arrow. Fig. 4 is drawn on a larger scale than Figs. l, 2 and 3 which are drawn on the same scale.

My improved fluid-conducting flue comprises two tubular metal sections A and B which are shown arranged horizontally and in line endwise, and 6 indicates the adjacent end-portions of said flue-sections. Said end-portions of the flue-sections extend into proximity to each other at their adjacent ends, but are spaced far enough apart endwise at said ends to permit the interposition between them of a rotary disk-valve C employed in controlling communication between said flue-sections, and said valve consists preferably of a circular metal plate provided at its periphery with gear-teeth 7 so as to form -a combined gear and valve. The valve C therefore extends between and faces adjacent ends of the Hue-sections A and B but has such dimensions relative to said ends of said flue-sections that its periphery and its axis are arranged externally of the passageway formed within and by said fluesections.

Preferably ea'ch end-portion 6 of each line-section has its bottom sloping upwardly, as at 8, Figs. 2 and 3, in the direction of the valve and has its sides diverging in said direction, as at 10, Fig. l. The sloping of the bottoms of adjacent end-portions 6 of the flue-sections upwardly and toward the valve permits the use of a valve which is considerably smaller in diameter than would be necessary if the flue-sections were not thus reduced in size vertically at their adjacent ends, and the divergence of the sides of said end-portions of the flue-sections toward the valve is not unimportant in that the lateral enlargement thereby attained of said end-portions is essential to substantially avoid reduction in the Huid-conducting capacity of said end-portions of the fluesections by the reduction in size vertically of said end-portions.

Preferably adjacent end-portions 6 of the flue-sections A and are provided externally at the faces of the valve with metal clamping members 12 which extend around or circumferentially of and are riveted or otherwise secured to the flue-sections.

Preferably the valve C is loosely mount ed on a horizontal pin D which is arranged longitudinally of the flue and below and externally of the passageway formed in and by the flue-sections A and B. rlhe pin D is supported from the clamping member 12 of the end-portion 6 of the flue-section A and extends, as shown in Fig. 4:, through said clamping member and longitudinally of said fine-section, and the valve is therefore supported from said clamping member and consequently from said Hue-section. It will be observed that the clamping member 12 of the iiuefsection A is arranged at one face of the valve and that the clamping member 12 of the end-portion 6 ofthe flue-section B is arranged at the other face of the valve, and that the valve is adapted to be clamped at its faces by and between said clamping members as will hereinafter more clearly appear. By my improved construction the pin D is unexposed to the action of any fluid passing through the iue.

The valve is provided between its axis and its periphery with a port 13 extending through the valve from face to face of the valve and having a wall 1Ll which (see Fig. 3) extends circumferentialljs.7 of said axis a distance somewhat less than half way around said axis and having another wall 15 which extends between the ends of the irst-mentioned wall, and it will be observed that adjacent ends of the end-portions 6 of the flue-sections substantially correspond in contour with the outline of the valve-port 155,V and that said port is arranged wholly above the axis of the valve in the open position of the valve, as shown in Figs. 3 and 1l, but obviously the valve has been actuated into its closed position andv communication between the flue-sections A and B is interrupted upon the rotation ofthe valve, when the valve. is free to rotate, far enough in either direction until said opening is in position below said axis.

The endeportion 6 of the flue-section B is provided externally with twoy brackets 1G arranged at opposite sides respectively of said flue-section, and the flue-section A is provided externally with two brackets 17 arranged at opposite sides respectively of said uevsection.

Two screws E are arranged at opposite sides respectively and externally of the endportion 6 of the flue-section A, which screws arein line endwise transversely of said fluesection. Unto. each screw E is screwed a spur-gear Gr which supports said screw and is supported from the adjacent bracket 17, and said bracket is contoured as required to permit endwise movement of said screw during the rotation of said gear, and means `for preventing movement ofsaid gear endwise of said screw are provided and comprise a shoulder 18 formed internally of said bracket at one end of the hub of the gear and a cross-bar 19 with which said bracket is provided at the other end of said hub. Each screw E is operatively connected at its outer end by a link e with the adjacent ends of the two links K of a toggle joint which is arranged longitudinally of the flue and extends between and is connected to the adjacent brackets 16 and 17 of the flue-sections A and B. One link of said toggle-joint is shown pivoted vertically at its outer end, as at 20, to the adjacent bracket 16 of the flue-section B, and the other link of said toggle-joint is shown pivoted vertically at its outer end, as at 21, to the adjacent bracket 17 of the flue-section A. The screw E at one side of the flue is right-handed and the screw E at the other side of the flue is left-handed, so that when the gears (if are simultaneously rotated in the same direction said screws are simultaneously shifted endwise but in opposite directions respectively. When the valve C is clamped by and between the clamping members 12 ofthe flue-sections A and B the links K of each togglejoint are somewhat out of line, as shown in Fig. 1, and obviously upon the shifting of the screws E endwise in the direction required to move said links into line said flue-sections are separated slightly farther than shown in Fig. 1 and consequently loosened relative to the valve G Ubviously when the valve C is clamped by and between the clamping members 12 of the flue-sections A andB the joints between the valve and said flue sections are substantially fluid-tight, and the valve must be loosened relative to the flue-sections before actuating the valve from one to the other of its positions.

Under the sloping bottom of the end-portion 6 of the flueesection A is located a shaft L which is arranged horizontally and transversely of said flue-section and supported from the brackets 17. rlhe` shaft L is parallel with the screws E and entends under said screws. rThe shaft L is operatively provided under each screw E with a pinion Z which meshes with an intermediate gear 22 supported from the adjacent bracket 17 and meshing withv the gear Gr engaging said screw, and said shaft is operatively provided at one end thereof with a sprocketwheel 23 which is actuated by a suitably applied and suitably driven chain 24:. lt will be observed therefore that the shaft L is intergeared with the screws E, and that said screws are actuated endwise toward or from each other according as said shaft is rotated in the one direction or the. other, and that consequently the toggle-jointsV are lsimultaneously operated to cause the valve to be clamped by and between; or rendered loose relative to the opposing faces of the clamping members of the fine-sections according as said shaft is rotated in the one or the other direction.

At the outer side of one of the brackets 17 is arranged a shaft R which is arranged horizontally and parallel with the axis of the valve C and (see Fig. 2) has bearing in a box 25 formed on said bracket, and said shaft extends into suitable proximity to the periphery of the valve and is operatively provided with a pinion r which meshes with the gear formed by the toothed peripheral portion of the valve. It will be observed therefore that the shaft R is intergeared with the valve. The shaft R is also operatively provided with a bevel-gear 26 which meshes with a bevel-gear operatively mounted on a shaft T which is arranged horizontally at 'the outer side of and at a right angle to and intergeared with the pinion-bearing shaft R and supported from an arm 28 of the adjacent bracket 17 and operatively provided at its outer end with a sprocket-wheel t driven by a suitably applied and suitably actuated chain 29.

By the construction and relative arrangement of parts hereinbefore described it will be observed that the valve has its gearforming peripheral portion extending outwardly beyond the fine-sections all around the latter and exposed to the atmosphere externally of the flue-sections, and that the shaft R and its pinion r and the shaft T are also arranged wholly externally o-f the flue-sections and exposed to said atmosphere, and consequently said shafts, said pinion and the valve are not overheated by hot gases or fluid conducted through said fluesections.
